ABSTRACT:
A carton blank and carton wherein an outer wall includes a die cut defining a cover and an inner wall disposed parallel to the cover inside the outer wall. The inner wall includes a die cut defining a removable plug. The plug is adhered to the cover so that when the consumer grasps the cover and opens it, the plug adheres to the cover and is removed from the inner wall, thereby creating a pouring opening. The plug preferably may be re-fit snugly within the pouring aperture when the cover is closed.
